>If I answer I dont say anything
>then they just hang up

I usually say hello once or twice before hanging up if no one says anything but lately I've been getting calls from out of state but they never say anything, so I hang up.

I would get pissed but I only get a spam call once a day, I've already block quite a few of them which ends up filling up my mailbox in a week & I don't know it's full until a friend calls me telling me they tried to leave a message but couldn't.
